Overclocking

The overclocking results listed in this section were achieved with the default fan and voltage settings as defined in the VGA BIOS. Please note that every single sample overclocks differently which is why our results here can only serve as a guideline for what you can expect from your card.

While the MSI card reaches lower clocks than other GTX 660s tested today, the resulting performance is better. We have seen the same behavior in our GTX 660 Ti reviews and suspect that MSI found a way to get more performance than other board partners out of their cards.

Important: Each GPU (including each GPU of the same make and model) will
overclock slightly differently based on random production variances. This table
just serves to provide a list of typical overclocks for similar cards, determined
during TPU review.

Overclocked Performance

Using these clock frequencies, we ran a quick test of Battlefield 3 to evaluate the gains from overclocking.
